With the exception of that function and the required structure
definitions, the whole code also works with i.MX53 (tested with LOCO
board), too. Also AN4581 [1] that describes HAB doesn't differentiate
between i.MX53 and i.MX6 in that case as they both use HAB v4.

I think you have more experience how to organize the code (I added a few
symlinks and modified only the Makefile, but I guess that symlink are
not the best solution).
